What are some good application security tools?

Good application security tools depend on what you're trying to protect: source code, APIs, web applications, cloud infrastructure, or running applications. For most development teams, the strongest approach is to combine several tools across the software development lifecycle rather than rely on a single security scanner.

Best application security tools by category

A practical shortlist of widely used tools, including open-source and commercial options.

1. Source code and code analysis (SAST)

These tools scan source code for vulnerabilities before the application is deployed.

Semgrep

Great starting point

Fast, developer-friendly static analysis with customizable rules for security bugs, insecure coding patterns, and organization-specific policies.

Best for: CI/CD integration, custom rules, Python, Java, JavaScript, Go, and more.

Website · Free and paid tiers

SonarQube

Finds security issues alongside bugs and maintainability problems, making it useful for routine code quality gates.

Best for: teams that want security and code quality checks together.

Website · Community and commercial editions

Checkmarx

Enterprise application security testing with source-code analysis and broader application security capabilities.

Best for: larger organizations with centralized security governance.

Website · Commercial

2. Dependency and software supply chain security (SCA)

These tools identify vulnerable third-party packages, outdated libraries, and supply-chain risks.

Snyk

Scans dependencies and can also analyze source code, container images, and infrastructure-as-code files.

Best for: developers who want security findings and remediation advice inside their workflow.

Website · Free and paid tiers

OWASP Dependency-Check

An open-source tool that identifies dependencies with publicly disclosed vulnerabilities.

Best for: budget-conscious teams and build-pipeline vulnerability checks.

Website · Open source

GitHub Advanced Security

Adds code scanning, secret protection, and dependency security capabilities to GitHub-based development workflows, depending on the plan and features enabled.

Best for: teams already using GitHub for repositories and pull requests.

Website · Plan-dependent

3. Web application and API security testing (DAST)

Dynamic testing examines a running application by sending requests and analyzing its responses. It's particularly useful for finding issues such as cross-site scripting (XSS), injection, and authentication weaknesses. Dynamic Application Security Testing (DAST)Vulnerability Scanning Tools

OWASP ZAP

Best free option

An open-source web application scanner and intercepting proxy with automation capabilities and CI/CD integrations.

Best for: learning AppSec, automated web scans, and security testing in development pipelines.

Website · Free and open source

Burp Suite

An industry-standard toolkit for hands-on web application penetration testing. Its proxy, request editor, scanner, and extensions help security testers investigate vulnerabilities.

Best for: penetration testers, security engineers, and manual vulnerability validation.

Website · Free Community edition and paid editions

StackHawk

Developer-focused dynamic security testing designed to run against applications and APIs during development and CI/CD.

Best for: teams that want repeatable security tests on every build or release.

Website · Free and paid options

4. Secrets detection

These tools look for accidentally exposed credentials, API keys, private keys, and tokens in repositories or commit history.

• Gitleaks - lightweight, open-source secret detection for repositories and CI pipelines. Website
• TruffleHog - scans repositories and other supported sources for secrets, with verification capabilities. Website
• GitHub secret scanning - detects exposed credentials in supported GitHub repositories, depending on the plan. Website

My pick: Gitleaks for a simple, automated starting point. Add secret scanning to pull requests and commits, and rotate credentials immediately if a real secret is exposed.

5. Container and infrastructure security

If your applications run in Docker, Kubernetes, or cloud environments, these tools help identify vulnerable images and insecure infrastructure configurations.

• Trivy - scans container images, dependencies, filesystems, and infrastructure configuration. Website
• Checkov - scans infrastructure-as-code for security and compliance misconfigurations. Website
• OWASP Dependency-Track - tracks software component inventories and associated supply-chain risks using software bills of materials (SBOMs). Website

These tools complement code scanners; they don't replace testing the application's actual behavior. www-community/pages/Free_for_Open_Source_Application_Security_Tools.md at master · OWASP/www-communityBest Application Security Tools 2026: 230 Reviewed

Which tools should you choose?

Your situation	Recommended starting stack
Individual developer or student	Semgrep + Gitleaks + OWASP ZAP
Small development team	Semgrep + Snyk + ZAP + Gitleaks
GitHub-centric team	GitHub security features + ZAP
Web application penetration testing	Burp Suite + ZAP
Docker/Kubernetes applications	Semgrep + Trivy + Checkov + ZAP
Large enterprise	Evaluate Checkmarx, Snyk, Veracode, or a comparable platform alongside specialized testing tools

These are starting combinations, not complete security guarantees. Validate scanner findings, test authentication and authorization flows, and include manual security reviews for business logic and other issues that automated tools can miss.

My recommended starting point

If I were setting up application security for a typical web application today, I'd start with:

1. Semgrep - scan source code for security bugs.
2. Gitleaks - prevent credentials from being committed.
3. Dependency scanning - catch vulnerable third-party libraries.
4. OWASP ZAP - test the running web application and its exposed endpoints.
5. Trivy - scan container images and deployment artifacts if applicable.

This gives you coverage across several major risk areas without requiring a large enterprise security budget.

To narrow this down, what kind of application security are you most interested in?

Application security (AppSec) tools are categorized based on what part of the software development lifecycle (SDLC) they protect and how they analyze code or infrastructure.
